The purpose of this study is to determine whether using a dietary education program based on learning cycle model has any significant effect on enhancing their nutrition knowledge, dietary behavior, science-process skill and scientific attitude. The subjects of this study were children in H and G daycare center in G City. The experiment group of this study was 16 children in the class of five-year-olds and 7 children in the class of four-year-olds who passed their birthday and became five-year-olds in H daycare center. The Analysis of Covariance(ANCOVA) and Pared t-test was conducted using SPSS WINDOWS 20.0 program. The results of applying dietary education program were as follows. Experimental group indicated enhancements between pre and post test of Nutrition Achievement Test, Nutrition Quotient for Preschooler, Science Process Skill and Scientific Attitude Assessment compare to comparative group. Therefore, we can conclude that the dietary education program does have effects on enhancing of nutrition knowledge, dietary behavior, science process skill and scientific attitude. The result of this study can be used as basic data to study dietary related factors that present importance of health dietary life of young children and need to provide educational experience of healthy diet for young children.

To establish good dietary behavior for middle school students, this study was conducted to analyze the needs of nutrition education and eating attitudes of 373 middle school students(boys 171, girls 202) in Hwaseong city. Using questionnaires, results were gathered and analyzed. Dietary behavior, food group intake and the needs of nutrition education were scored by a five-point Likert scale. Chi-square and student t-test were done for significant gender difference. The correlation between the needs of nutrition education with dietary behavior and food group intake was obtained by Pearson's r. The dietary attitude of 'try to eat first' and 'eating fast' were higher score in boys than in girls(p<0.05). Most of the students thought they didn't have any nutritional problems(71.8%). Nutrition education was considered necessary(54.9%) for proper growth and development(53.0%) in middle school. But 45.1% of students did not suggest by the reasons of 'short time to change'(28.2%), 'more effective in home'(27.4%). The appropriate time of nutrition education was pre-school(28.2%) or elementary school(27.4%), once a week(boys 51%, girls 71.3%) in frequency(p<0.001), and the information acquired by TV/Radio(30.0%) and internet(26.6%). Students(46.0%) wanted to know about 'growth and nutrition'. They were to learn information on the 'healthy growth'(4.10) and 'adolescent nutrition'(4.03). The vegetables group consumption and the thought of dietary attitude 'try to modify bad eating habits' were correlated with almost all categories of desired nutrition education. Through these results, good eating habits would be attained by nutrition education. A nutrition education program would require an expert teacher for middle school students.

This study was implemented to understand the motivation factors for $2^{nd}$ grade schoolchildren that effect on their preference for the sweet taste. The subjects included were 118 children (59 boys and 59 girls) and 118 children's guardians, from one elementary school. Children participated in sweet preference test and questionnaire survey with researcher's guidance provided in the school. Children's guardians were asked to fill out the questionnaire via home-letters. The results were as follows: 59% of the children preferred the cocoa beverage with the highest concentration of sugar among five cocoa beverages (0%, 2.5%, 5%, 7.5%, and 10% of sucrose/milk volume). The variables consisted of affective attitude, cognitive attitude, self-efficacy, parenting style, and sweets frequency. According to the analysis, sweet preferences were correlated with children's affective attitude (r=-0.207, p<0.01), self-efficacy (r=-0.288, p<0.01), frequency of drinking carbonated beverage (r=0.272, p<0.01), preference for yogurt (r=0.184, p<0.05), and preference for sweet bread (r=0.226, p<0.05). These results indicated that children can be more affected by affective attitude than cognitive attitude, and self-efficacy can be an important motivation factor to control the eating behavior related to sweets. Therefore, nutrition educators need to focus on developing various methods related to increasing self-efficacy for encouraging and motivating healthy eating behavior in children.

This study examined the proper roles of dietitian and nurse-teacher in the weight control program (WCP) in schools and the effect of the WCP on subjects with respect to anthropometric measurements, nutrition knowledge, dietary attiude, and behavior changes. The program consisted of six sessions of nutrition education and frequent face-to-face nutrition counseling. Subjects were 22 obese children in the 4th and 5th grade who underwent counseling and 18 obese children in another school who served as a control group. After two months of WCP, obesity index such as .elative body weight (RBW, from 135.7 to 132.5), tricep skinfold thickness (TSFT, from 34.9 to 32.8 mm), and body fat content (from 32.0 to 29.8%) had decreased significantly in the experimental group, while the control group showed no significant differences in these indices. The reductions in obesity indices were maintained in the experimental group except for fat content (32.6%), which returned to its original value within six months. The control group significantly increased fat content in the same period (from 31.2% to 36.2%). Both groups decreased RBW, TSFT, and fat content while midarm circumference and waist/hip ratio remained the same after one year. Subjects' nutrition knowledge was improved with average test scores from 15.1 to 16.7 while nutrition attitude and behavior test scores remained unchanged suggesting that behavior modification may require more time than knowledge acquirement. These results suggest that proper nutrition counseling can initiate weight reduction. However, the maintenance of controlled weight requires changes in attitude and behavior which have not been achieved by the present WCP. The role of school dietitian for WCP in this study was limited to assisting the nurse-teacher in nutrition education. Expansion of dietitian's role in nutrition education and counseling is needed.

Objectives: The purpose of this study was to investigate the perception of nutrition teachers and the factors influencing their intention toward sustainable dietary education utilizing the theory of planned behavior (TPB). Methods: The self-administered online survey was completed by nutrition teachers in Jeollanam-do, South Korea. A total of 151 valid questionnaires were analyzed. Factor analysis and multiple regressions were employed to test the research model. Results: The study findings demonstrated that all TPB variables significantly influenced the sustainable dietary educational intention, with the degree of influence ranking as follows: external perceived behavioral control (β = 0.417), attitude (β = 0.240), internal perceived behavioral control (β = 0.207), and subjective norms (β = 0.181). For external perceived behavioral control, nutrition teachers and elementary schools exhibited higher levels compared to dietitians and middle/high schools, respectively. The participants in sustainable dietary education training programs exhibited a higher level of internal perceived behavioral control compared to those who did not participate. The highest perception levels were reported for attitude (4.26), followed by subjective norms (4.02), internal perceived behavioral control (3.67), and external perceived behavioral control (3.20). Conclusions: This study affirmed that the TPB variables elucidated the sustainable dietary educational intentions of nutrition teachers. The significant impacts of external and internal perceived behavioral control, attitude, and subjective norms on educational intentions were confirmed. Consequently, proactive support from schools and governments is essential to enhance the facilitating factors and mitigate the barriers toward sustainable dietary education in schools.

This study was conducted to identify adults' knowledge, attitude, dietary behavior, and lifestyle for cancer prevention, and to examine the relation between these variables. The participants were 414 adults in the Jeonbuk area. The data were analyzed using Pearson correlation coefficients, ANOVA and Duncan test with SPSS v. 12.0. The score for participants' knowledge about cancer was 23.98 points of a possible 30, the score for attitude towards cancer was 44.46 points of a possible 55, the score for preventive dietary behavior for cancer was 36.79 points of a possible 55, and their score for preventive lifestyle for cancer was 29.76 points of a possible 40. The knowledge, attitude towards cancer, dietary behavior, and lifestyle for cancer prevention showed significant differences according to the general characteristics (e.g., age, religion, monthly income, educational level, job, health condition, and interests). There was a significant positive correlation between knowledge about cancer, attitude towards cancer, dietary behavior, and lifestyle for cancer prevention. Dietary behavior for cancer prevention showed a positive correlation with lifestyle for cancer prevention. In conclusion, it is necessary to consider the related factors for the development and implementation of systematic education programs that can encourage and promote preventive health behavior for cancer among adults.

BACKGROUND/OBJECTIVES: Excessive sugar intake is one of the causes associated with obesity and several chronic diseases prevalent in the modern society. This study was undertaken to investigate the effect of parenting variables based on the theory of planned behavior, on the sweetness preferences and sweets intake of children. SUBJECTS/METHODS: Parents and their children (n = 103, aged 5-7 years) were enrolled to participate in a survey for this study, after providing the required informed consent. Parents were asked to fill out a self-administered questionnaire at their residence. The sweetness preference test for children was conducted at a kindergarten (or daycare center) by applying the one-on-one interview method. RESULTS: The children were divided into two clusters categorized by the K-mean cluster analysis: Cluster 1 had higher sweetness preference (0.42 M sugar, 35%; 0.61 M sugar, 65%); Cluster 2 exhibited lower sweetness preference (0.14 M sugar, 9.5%; 0.20 M sugar, 9.5%; 0.29 M sugar, 81%). Cluster 1 had a higher frequency of sweets intake (P < 0.01), and lower sweets restriction (P < 0.05) and nutrition quotient score (P < 0.05). Sweets intake was negatively correlated with the nutritional quotient (r = -0.204, P < 0.05). The behavioral intention of parents was higher in cluster 2 (P < 0.05), while affective attitude, feeding practice, and reward were higher in cluster 1 (P < 0.001, P < 0.05, and P < 0.01, respectively). Furthermore, behavioral intention of parents showed a negative correlation with affective attitude (r = -0.282, P < 0.01) and feeding practice (r = -0.380, P < 0.01), and a positive correlation with subjective norm (r = 0.203, P < 0.05) and parenting attitude (r = 0.433, P < 0.01). CONCLUSIONS: This study indicates that the sweetness preferences and sweets intake of children is related to the parent's affective attitude, feeding practice and reward. We suggest that to reduce the sugar consumption of children, guidelines for access to sweets and pertinent parenting practices are required.

The enforcement and its effect of weight control program including nutrition education, exercise and behavioral modification therapy during 20 weeks were studied in primary school obese children. The sample consisted of treatment group(n=19) and control group (n=23). To evaluate the effects of weight control program, treatment group took pretest and posttest for nutrition knowledge, attitude and food habits. Nutrient intakes, serum lipid levels and anthropometric values were also measured. After weight control program, body weight of treatment group significantly decreased from 47.0$\pm$9.0kg to 45.9$\pm$8.5kg(p<0.001), but than of control group increased from 47.8$\pm$8.1kg to 49.0$\pm$8.7kg (p$\leq$0.05). Obesity index showed decline of 8.6% for treatment group and gain of 0.7% for control group. After self-control period, body weight and relate index in both groups were increased. For the nutrition knowledge test results, the posttest mean scores of treatment group showed the significant increase(p<0.001). For the attitude toward nutrition and food habit results, the posttest mean scores increased significantly (p<0.05, p<0.01). There was a decline of 28% in serum triglycerides, whereas serum total cholesterol increased 11% of baseline. These findings suggest that well-combined weight control program for obese children may result in a substantial loss of body weight during 14 weeks. In addition, these reuslts indicate that weight redution through weight control program can be a viable approach to help normalize serum lipids in obese children. Finally, these data suggest that it may be important to identify that affect weight loss and maintenance, and to examine how to manipulate these factors in weight control program.

The purpose of this study was to assess the effect of nutrition education by the difference of BMI(Body Mass Index) group for adults at rural area. Eighty four adults (mean age : 55.9$\pm$11.8) participated in nutrition education program. Data collection includes measured physical status and serum collections for health status. The impact of nutrition KAP (knowledge attitude and practice) and retention was examined among participants who were assessed at program entry, 3 times of education and 1 month of follow-up. The results were as follows: The participants were composed 14 persons of under 20kg/$m^2$ of BMI, 40 persons of 20-25 and 27 persons over 25 of BMI , female 60 persons but male 23 only. Serum albumin and calcium content of female(3.5$\pm$1.2g/㎗, 7.5$\pm$3.9mg/㎗) were significantly lower than males(4.7$\pm$0.9g/㎗, 11.2$\pm$4.6mg/㎗) but there was not significantly different with BMI groups. Serum TG and cholesterol contents of over 25kg/$m^2$ of BMI group(157$\pm$87mg/㎗, 249$\pm$16mg/㎗) were higher than other groups, but significantly different in cholesterol contents only. Via the 10 questions of nutrition attitude, the participants improved significantly between pre and post education(the score of pre, post and after 1 month, 6.5$\pm$1.8, 7.2$\pm$1.5, 7.2$\pm$1.9), and were also attributed to better personal feeling health by modified CMI test, but dietary food habit was not significantly improved. As the differences of BMI groups were compared, 20-25kg/$m^2$ group had better the effect of nutrition education score than other groups, and female had better nutrition attitude and practice score than male.
